A ceding insurer fears its reinsurer may not pay claims a decade from now. One lump-sum payment ends the relationship today. That deal is a commutation.
The cedant returns the reinsurance recoverable asset and takes back the liability. The reinsurer pays cash and releases the assumed reserves. Both sides get certainty.
The cedant measures against its own book. It receives but eliminates the recoverable it carried, which need not equal the reinsurer's reserve. Its gross reserves stay unchanged; net reserves rise toward gross because the ceded credit is gone.
KEY: Because the payment is discounted below nominal reserves, the reinsurer typically books a gain and the cedant a loss on the same transaction. Each side may still view the deal as favorable given its own reserve and collectibility judgments.
The gain or loss is ordinary income, recognized when the contract terminates. Because loss reserves sit unpaid for years, tax law will not let you deduct them at face value today and forces a present-value view instead.
Common mistakes
- Treating the payment as full nominal reserves. The commutation payment is discounted, typically below the $10,000,000 nominal reserve, creating the gain and loss.
- Running the effect through investment income. The commutation result flows through underwriting/incurred losses, not investment income.
- Using statutory reserves for the tax gain. Tax uses the IRC 846 discounted reserve, so the taxable gain ($800,000) is smaller than statutory ($1,800,000).
Bottom line
- A commutation terminates a reinsurance contract: the reinsurer pays a single settlement and the cedant reassumes all future liabilities.
- The commutation payment is usually below nominal reserves, reflecting time-value discount and negotiation.
- Reinsurer books a gain equal to its own carried reserves released minus the payment made.
- Cedant books its own result: cash received minus the recoverable it carried, usually a loss. The two results mirror only when both parties booked the same amount.
Exam shortcut
Reinsurer result: its carried reserve minus the payment. Cedant result: cash received minus its own carried recoverable. Flip the sign only when the problem states both parties booked the same amount. For any tax question, swap the statutory reserve for the discounted IRC 846 reserve before subtracting the payment. The book-tax difference equals the reserve discount. If asked "why commute," list finality, capital release, credit-risk removal, and ending administration.
